INSTALLATION PROCEDURE
Exercise care when handling this machine. a sudden jolt or jar may cause serious
damage.
Do not remove the shipping skid until machine has been moved to a point of
installation. The skid is designed for easy and safe handling of your machine.
Raise or lower the machine to the desired operating elevation using the leveling jack
screws and level the machine.
A great deal of trouble may be caused if the current is supplied by lines which are
not heavy enough. if this occurs, the motors and controls cannot operate at their full
capacity and over heating may result. A similar condition will exist if poor electrical
connections are made. It's therefore worthwhile to make sure that everything is
electrically correct.
Electrical polarity must be supplied to the machine exactly as shown on the electrical
diagram. Power must be supplied to L1 side of the circuit and the L2 side will be
neutral. If this is not correct, the circuit protectors (ECP 1) will trip out because of a
short circuit.
The air to the machine should be clean and dry, as the filter is only meant to remove
minor particles or slight amounts of moisture. Dirt or moisture in the air line can
cause the erratic operation of control valves.
Connect the air supply to an air source with a minimum line pressure of 80 PSI.
Before starting the machine, load the tape cartridge with tape and thread the tape.
See threading diagram on tape unit.
For proper start-up procedure see the start-up procedure section of this manual.

SEQUENCE OF OPERATION
INITIAL CONDITIONS:
A. MAIN AIR ON
B. POWER SWITCH OFF.
C. VACUUM CUP TROLLEY CYLINDER IS EXTENDED. (SOL. 5)
D. MINOR FLAP FOLDER CYLINDERS ARE RETRACTED. (SOL. 6)
E. CASE PUSHER CYLINDER IS RETRACTED. (SOL. 4)
F. VACUUM SWITCH IS ON.
GENERAL SEQUENCE:
1. Press the "START" push-button (PB 2). Motor contactor (M1) is energized and
the motor starts.
2. Normally open contact (M1) closes, programmable controller is energized, and
the sequence starts.
3. The case pusher and vacuum cup trolley go to home position.
4. As soon as proximity switches 2 and 3 are activated , the vacuum cup trolley
(output 102) moves forward to pick-up a blank.
5. At the extended position, the vacuum cup trolley activates proximity switch 1
(input 002) energizing timer 4. After a pre-set time, timer 4 times out, de-energizing
vacuum cup trolley solenoid (output 102).
6. The vacuum cup trolley then returns to the home position, activating proximity
switch 2 (input 003) energizing the minor bottom flap folders (output 104).
7. Proximity switch 2 energizes timer 3. After a preset time, timer 3 times out de-
energizing the vacuum solenoid (output 103). The formed case is released, ready
for case transfer.
8. As the chain lug is detected by photocell 1 (PC 1), the internal relay 1004 turns on
the case pusher solenoid (output 106), allowing the case pusher to move forward
and push the formed case towards the feed rollers, and then into the chain lug drive.
